I died twice on the last level of challenge mode while going through the tunnel of the safehaven. I think your dinosaur should be safe immediately after you cross the threshold.
I played on medium difficulty, and the enemies seemed much harder than usual, then I played a game on which I lowered my team to very easy, and it appeared to be exactly the same. What's up with that?
I know I never said the obstacles don't disappear completely, although I do notice this. I didn't notice the invincibility timer. Despite this, I still believe the obstacles should be brighter. And as far as I know, the vehicle does not move with the pressure applied to the keys, but with how long the keys are held down. And my thoughts on the pausing penalty have changed, and I was aware of the cheating before posting my last comment. I have also read a comment about chatting(George 1982)that you may have to pay 250 points when you talk to your friends, hence my current thought on the pause penalty. It is a great game, but I still think it could be a bit better, 4/5.
Good game, but unfair. First of all, the invincibility shouldn't make the obstacles invisible, It should make them still visible, and you should have a timer on invincibility. I got the powerup then crashed into a stalagmite when it was expired. Second of all, the vehicle shouldn't move so swiftly. Lastly, The penalty for pausing doesn't make sense. You don't have to pay 250 points just to use the bathroom. 3/5
